OPC UA Server Connected, all tags bad

The server is telling you there are already too many monitored items created. If there are other OPC UA clients connected you might need to budget how many items each can subscribe to. You might even need to do that with just Ignition connected. You could also put all these tags into a Polled/Read mode scan class instead, and they’ll be polled instead of subscribed on the server.
